A) zero
B) 2
C) 4
D) 8
Correct Answer: C
Solution :
Given, \[{{x}_{1}}=a\cos 500\pi t\] \[{{x}_{2}}=a\cos 508\pi t\] \[{{\omega }_{1}}=2\pi {{n}_{1}}=500\pi \] \[{{\omega }_{2}}=2\pi {{n}_{2}}=508\pi \] \[n=\frac{{{n}_{2}}-{{n}_{1}}}{2}=\frac{508-500}{2}\] \[n=\frac{8}{2}=4\]You need to login to perform this action.
